ICL5102HV Data Sheet ICL5102HV PFC + Resonant Half-Bridge Controller for LED Drivers 2nd Generation Datasheet Rev1.2 Features Integrated two stage combination controller allows for reduced number of external components, optimizes Bill of Materials (BOM) and form factor. PFC controller with Critical Conduction Mode (CrCM) + Discontinuous Conduction Mode (DCM) Resonant Half-Bridge (HB) controller with fixed or variable switching frequency control Maximum 500 KHz HB switching frequency and soft-start frequency up to 1.3 MHz Resonant HB Burst Mode (BM) ensures power limitation and low standby power < 300mW. Supports universal AC input voltage (90 to 480 Vrms) nominal Excellent system efficiency up to 94% THD optimization ensures Low harmonic distortion (Total Harmonic Distortion (THD) < 5%) down to 30% nominal load. Integrated High Side MOSFET driver Comprehensive set of protection features with auto-restart reaction: Input brown-out protection PFC bus over-voltage protection PFC over-current protection Output over-voltage protection (OVP) Output over-current/short circuit protection (OCP) Output over-power/over-load protection (OPP) Capacitive mode protection External over-temperature protection (OTP) Potential applications Offline LED Drivers for commercial and industrial lighting up to 350 W High density AC/DC power supply Product validation Product Type Package ICL5102HV PG-DSO-19 Datasheet Please read the Important Notice and Warnings at the end of this document V 1.2 www.infineon.com page 1 of 34 2019-04-01 CV & CC Regulator L4 4 ICL5102HV PFC + Resonant Half-Bridge Controller 2nd Generation Description ROVP 2 ROVP 1 LPFC Cr1 The ICL5102HV is a highly integrated multi-mode (CrCM and DCM) PFC and resonant HB combination controller. L4 3 The integration of PFC and HB into a single controller enables reduction of external components and optimizes Lm PFCZCD Cr3 VOUT + VACIN performance by harmonized operation of the two stages. Lr HSGD VOUT - HSVCC PFCGD The two-stage approach divides the PFC responsibilities from the output current regulations functions. This HSGND ensures low variation in the output voltage and current and allows for low THD, high power factor and a greater Cr2 PFCVS DBO1 DBO2 ability to withstand AC line perturbations. The multi-modLSGD e operation of PFC converter provides excellent PFCCS LSCS efficiency over the whole load range. RBO1 Resonant HB converter supports both LLC and LCC topologies with fixed or variable switching frequency control for highest efficiency and the BM enables the low standby power consumption. RBM DA SFH617-A3 A comprehensive set of protection features with auto-restart ensures the highest safety and reliability of the CVCC RBM RBO2 components and overall system.
